摘要： A method of forming a metal-graphene composite includes coating metal components (10) with graphene (14) to form graphene-coated metal components, combining a plurality of the graphene-coated metal components to form a precursor workpiece (26), and working the precursor workpiece (26) into a bulk form (30) to form the metal-graphene composite. A metal-graphene composite includes graphene (14) in a metal matrix wherein the graphene (14) is single-atomic layer or multi-layer graphene (14) distributed throughout the metal matrix and primarily (but not exclusively) oriented with a plane horizontal to an axial direction of the metal-graphene composite.

摘要： A method for manufacturing a continuous sucker rod coil, wherein the method includes the step of selecting a plurality of input coils, each input coil having the same uniform hardness, and each input coil having two free ends. The method further includes the step of fusing adjacent free ends of adjacent input coils together to form one continuous length of rod, the fusing creating fused areas and a heat-affected zone at each fused area. The method also includes the step of treating each of the heat-affected zones to alleviate irregularities induced during fusing. Additionally, the method includes the step of winding the continuous length of rod into a finished coil.

摘要： A high-performance Nb3Al extra-fine multifilamentary superconducting wire is produced simply and inexpensively through the improvement of critical values, Tc, Hc2 and Jc, without the addition of third elements such as Ge, Si and Cu. A first rapid heating and quenching treatment is applied to an Nb/Al composite wire having an atomic ratio of Al to Nb from 1:2.5 to 1:3.5 and having an extra-fine multifilamentary structure to form a BCC alloy phase comprising Nb with Al supersaturatedly dissolved therein wherein the treatment comprises heating the composite wire up to a temperature not lower than 1900° C. within two seconds and then introducing it into a molten metal at a temperature not higher than 400° C. to rapidly quench it. The wire is subjected to a second rapid heating and quenching treatment to form an A15-Nb3Al compound having a low degree of crystalline order but having an approximately stoichiometric composition wherein the second treatment comprises heating the wire up to a temperature not lower than 1500° C. within two seconds and then introducing it into a molten metal at a temperature not higher than 400° C. Then, an additional heat treatment is conducted to improve the degree of crystalline order of the Al5-Nb3Al compound having an approximately stoichiometric composition.

摘要： Twin metal billets are fed to dual circumferential grooves formed in a rotating wheel. The billets are advanced first to a wedge-shaped gap which deforms the billets and are then advanced to a die. The die has a die opening with a circumferentially discontinuous, annular cross-section. The metal from each billet merges in the die opening and exits therefrom in the form of a slit tube. The tube is then opened and flattened to form a flat strip by advancing the slit tube over a forming member having a progressively increasing width.

摘要： A bow beam, as well as a method of making the beam for the roof of truck trailer, is described as being initially extruded in a U-shape with a flat web which is heavier than a pair of legs which extend from the web. The extruded beam is then placed in a press where the free ends of the legs are bent to form a bow in the topside of the beam in spaced relation from the flat bottom web. Thus, the strength of the beam is optimized with a minimal amount of material.

摘要： Method of producing bright steel from rolled steel wire, in which the diameter of the rolled wire is first reduced by passing the same through a calibrating device, preferably a reducing mill, whereby internal stresses assymetrical with respect to the wire axis are produced in the wire, thereafter removing peripheral surface portions from the wire and subsequently straightening the wire, and subjecting the wire before removing peripheral surface portions therefrom to a radial bending force rotating about the axis of the wire to plastically deform the latter to thus reduce the assymetrical internal stresses to thereby improve the perfect roundness of the finished product.
